Understanding and Setting Up Two-Factor Authentication

What is Two-Factor Authentication?

Two-Factor Authentication (2FA) is a security measure that requires users to verify their identity through two separate methods before gaining access to an account or system. Typically, this involves:

1. Something you know (e.g., a password or PIN).
2. Something you have (e.g., a smartphone, security key, or a one-time code).

For example, if you connect your phone number as a second verification method, your phone may be texted a temporary code that you must input to sign into the account.

This layered approach significantly enhances security, because if your password is compromised, unauthorized access is still unlikely without the second verification.

When Should You Use It?

📌 Many platforms will ask you upon log in if you would like to set up 2-Factor Authentication

2FA should be enabled wherever possible, particularly for:

• ✅Email accounts, as they are often linked to other online services.
• ✅Banking and financial platforms, to protect sensitive information and transactions.
• ✅Social media accounts, to prevent unauthorized access and misuse.
• ✅Work-related systems, to safeguard sensitive business data.

Essentially, if an account holds personal, financial, or sensitive information, 2FA is a must for enhanced protection.
